Extra U(1), effective operators, anomalies and dark matter
Emilian Dudas, Lucien Heurtier, Yann Mambrini +1
A general analysis is performed on the dimension-six operators mixing an almost hidden Z' to the Standard Model (SM), when the Z' communicates with the SM via heavy mediators. Thes…
Thermal and non-thermal production of dark matter via Z'-portal(s)
Xiaoyong Chu, Yann Mambrini, Jérémie Quevillon +1
We study the genesis of dark matter in the primordial Universe for representative classes of Z'-portals models. For weak-scale Z' mediators we compute the range of values of the ki…
Gauge Coupling Unification and Non-Equilibrium Thermal Dark Matter
Yann Mambrini, Keith A. Olive, Jeremie Quevillon +1
We study a new mechanism for the production of dark matter in the universe which does not rely on thermal equilibrium. Dark matter is populated from the thermal bath subsequent to…
